WS_E_ENDPOINT_ACTION_NOT_SUPPORTED
WS_E_ENDPOINT_ACTION_NOT_SUPPORTED is a Windows Web Services API HRESULT. It means that the service endpoint rejected the requested message action or operation because it is not implemented, published, or permitted by that endpoint.
What to check for WS_E_ENDPOINT_ACTION_NOT_SUPPORTED
- Compare the requested action, SOAP action or operation name with the active service contract.
- Check client and server versions, routing rules and endpoint bindings after deployment changes.
- Do not reinterpret an unsupported action as a transport failure.
Diagnostic interpretation
This result has the HRESULT value 0x803D0011. AllStat records the condition as “The operation was not supported by the remote endpoint.”.
Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the ws / endpoint / action / supported operation.
- compare the failing machine with a working one at the same configuration boundary: component version, policy, registration, identity, and target resource.
